Peb txhua tus paub tias nyob rau ntau lub chaw hauv lub neej, ntau yam khoom siv vuam siv tshuab. Nws tuaj yeem hais tias welding yog qhov txhia chaw. Yog li cas txog laser welding tsis zoo? Koj paub ntau npaum li cas txog kev siv laser welding ntau npaum li cas? Dab tsi yog qhov pib laser welding?
Nws to taub tias qhov tsis siv lub tshuab laser tsis yog lub voj voog txoj kev siv lub zog siab ceev laser nqaj ua ib qhov chaw muaj cua sov. Laser welding yog ib qho tseem ceeb ntawm kev siv cov khoom siv laser tshuab. Laser welding yuav tsum tau pom tau hais los ntawm kev nrig laser nruam lossis pulsed. Lub hauv paus ntsiab lus ntawm laser welding tau muab faib ua thooj txav mus rau hauv kev sib tshuam thiab laser tob vuam.
Lub zog ntim qis dua li 104 ~ 105 W / cm2 rau cov khoom siv hluav taws xob vuam vuam. Nyob rau lub sij hawm no, qhov tob tob tob yog qhov ntiav thiab qhov vuam voog qeeb qeeb. Thaum lub zog ntim qis dua 105 ~ 107 W / cm 2, qhov hlau ntim yog siv rau qhov "qhov" nyob rau hauv qhov kev txiav txim ntawm cov cua sov kom tob tob fusion welding. Lub vuam ceev yog ceev thiab qhov piv piv yog loj.
Los ntawm cov kev taw qhia kev pom, laser welding yog ib txoj hlua tseem muaj zog. Nyob rau hauv daim ntawv thov kev pab, nws yog dav siv los ntawm cov tuam txhab. Laser welding muaj lub zog zoo dua qhov feem cuam tshuam hauv kev lag luam kev lag luam vim laser vuam yog nyob rau hauv qhov chaw. Technically, nws yog nyob rau hauv lub forefront, thiab nws siv cov khoom nyob hauv tsev thiab txawv teb chaws.
Lub voj tseem ceeb ntawm kev siv laser vuam yog tias cov nqaj hlau laser siv los ua lub vuam vias qhov chaw, thiab qhov cuam tshuam yog nyob rau hauv cov hlua khi, thiab tom qab ntawd ces tus nqaj yog zwm los ntawm kev sib tsho los ntawm reflecting tus thawj los yog lub lens, yog li ua welding. Vuam yog kev tsim, thiab nws feem ntau tsis muaj rau cov lag luam me. Yog li ntawd, nws yog siv hauv cov lag luam loj nyob hauv tsev thiab txawv teb chaws.
Qhov laser welding tsis siv lub laser-high-power laser los ua kom pom cov khoom siv kev sib txuas ntawm cov khoom siv kev sib txuas, yog li ntawd cov khoom sib cais absorbbs lub zog laser thiab ces melts los yog vaporizes thiab cov ntaub ntawv ua ib lub pas dej ua ke ua ke, thiab solidifies thiab koom nrog cov txheej txheem cua txias. Laser welding tsuas muaj cov yam ntxwv ntawm cov cua kub thiab cov cua kub muaj peev xwm, cov vuam voog deformation thiab ceev ceev vuam ceev.
Tsis siv neeg laser welding radiates ib kab teeb laser nrog cov kev coj zoo heev, kev ci ntsa iab, siab siv, siab monochromaticity, siab ua ke, thiab lwm yam ntxiv rau hauv thaj tsam ntawm qhov workpiece. Tom qab lub teeb laser yog teem rau ntawm qhov system kho qhov muag, lub lens kev kub siab yog Lub hwj chim ceev yog 104-107W / cm2. Los ntawm kev sib txuas ntawm lub laser thiab cov khoom yuav tsum tau soldered, lub welded feem ua ib lub siab concentrated cua sov thaj chaw hauv thaj av nyob rau ib lub sij hawm luv luv. Lub tshav kub tau yaj thiab cov siv lead ua kom tau zoo tom qab tawg lawm. Cov kab yas txha thiab cov hlua khi.
